Since Nikon launched the D750 in 2014, the successor to this hot-selling model has become a frequent customer of rumors. In 2018, Nikon opened the Z system, and the appearance of the Z6 made many people feel that the possibility of the D750 follow-up machine was less likely to be launched. However, the turn of the game took a turn. Just after the 2020 New Year, Nikon officially released the D750 successor-D780 on January 7.
Since it is the successor to the D750, the D780 should naturally adhere to the “small With the characteristics of body and high performance, we learn from our strong points to further improve this product. Nikon first enhanced the performance of the SLR system, such as the use of about 180,000-pixel RGB sensor, 1/8000 second shutter, D5 autofocus algorithm, etc., and then complement the shooting performance of the D series SLR live view. The reason why the D780 will not be launched until 2020 is largely because it has to wait for the new mirrorless features of the Z system, such as the new back-illuminated sensor, EXPEED 6 processor, 273-point focal plane phase detection AF, 4K super-sampling video, eye Partial detection AF and so on, so the introduction of Z6 features can completely improve the shooting experience even when framing. If Z7 is the mirrorless version of D850, then D780 is SLR version Z6. The biggest difference in concept between D780 and D850 is in real-time view. D850 is still a traditional SLR camera, and it is still using “original” in live view. Contrast detection AF. So what is the paper strength of D780? Below we will compare D780 with D750, Z6, EOS 6D Mark II parameters:
From the point of view of specification comparison, D780 combines Nikon mid-range SLR and the latest technology on Z6, such as back-illuminated CMOS, EXPEED 6 processor, about 180,000 pixels RGB sensor, 273-point focal plane phase detection AF 900 second shutter, eye detection AF, 4K 30p /1080 120p, etc., at the same time also introduces 1/8000 second shutter and cancel internal flash, familiar with digital SLR users know that this marks an improvement in the “level” of the D780. In addition, D780 externally recorded video also supports composite logarithmic gamma, a feature that has never been carried by the Z series. Compared with the previous generation, due to the new sensor and processor, the D780 has the same image quality as the Z6 and improved high-sensitivity performance. The continuous shooting under OVF has not improved much. Due to the 51-point AF system combined with the new RGB sensor, and the D5 AF algorithm , Automatic area detection performance will be improved; LV live view shooting performance is improved the most, including phase detection tracking focus, 4K sampling video, eye detection AF, etc., with the flip screen greatly enhance the multi-angle shooting experience. In addition to the pixel value of the D780, all parameters are fully suppressed by the EOS 6D Mark II, which is close to the EOS 5D Mark IV. Of course, the two Canon products were launched 3-4 years ago, and now they have reached the update period. As for the actual shooting performance of the D780, I will test it in detail later.
D780 front and back
D780 top line
Nikon D780 appearance The design has absorbed the characteristics of the D850, especially the lines on both sides of the “warship roof” are deeper than the D850, making it tougher. In addition, the “changes” such as the D780’s cancellation of the built-in flash on the top of the camera and the front focus assist light all demonstrate the further professionalization of this product.
Z6 and D780
D780 handle concave Groove
D780 is a circle smaller than D850 in volume, and a bit larger than the previous generation D750. Both the width and height are increased by 2-3mm, but everyone should pay attention to the thickness. D780 is 2mm thinner than D750. The thickness of the camera body is reduced, the biggest advantage is that the handle will become deeper and longer, which is convenient for holding for a long time.
back cover and The top cover is made of magnesium alloy
Airframe sealing design
In the airframe structure and material, D780 inherits the one-piece structure of D750, the back cover and top cover are made of magnesium alloy, and the front body and front cover may be the same as D750 , The use of carbon fiber composite materials to achieve a strong frame, while reducing the overall size and weight. Although D780 is slightly larger than D750, the weight of the body is only increased by 5g, and the user will not perceive the difference.
D780 model change In order to be printed on the body
In addition, Nikon’s new reflector lowers the balancer to greatly reduce mechanical vibration and obtain a stable viewfinder image during continuous shooting.
D780 body Incorporating some D7500 designs, such as the operating layout around the shutter button. Starting from the Nikon D5, the D series of high-end SLRs all use the left video recording button, the middle ISO button, and the right exposure compensation button.
The design of the left shoulder of the camera is the same as that of the D750, the upper layer shooting mode dial, the lower layer In order to release the mode dial, it is worth noting that the “scene mode” common to low-end and mid-range cameras has been cancelled on the shooting mode dial, and only the “special effects mode” is retained.
The buttons on the left side of the screen on the back of D780 are the same as those on D7500. The D750’s independent metering mode button is cancelled, and the D780 uses the zoom button as well as the D7500.
The right side of the screen has changed a lot, Nikon will change the LV button and take pictures /Move the video selection lever to the thumb operation area on the top of the fuselage, which is convenient for users to switch quickly. This shows how much Nikon attaches importance to the experience of real-time view photography and video recording on this camera. D780 adds an independent AF-ON button in the thumb operation area on the back to further enhance the operability.
The AE-L/AF-L button moves down to the original D750 info button. The info button and i button are the same as D7500, but opposite to D750.
D780 flip screen
The screen of the D780 is similar to that of the D850, with a 3-axis hinge structure that can be tilted up or down. The resolution of the display has been increased to about 2.359 million points, which is equivalent to that of the D850. Users can clearly view image details and confirm the focus. The color of the screen can be customized to match the computer display for image editing. In addition, D780 is the same as D850. Realize the touch control of the playback menu/menu operation. It should be noted that by pressing the i button, the D780 provides a new live view UI interface, which is the same as the Z6. The user can specify 12 functions and cell positions. The user can change the settings through touch operation or the dial button.
In terms of interfaces, Nikon D780 has richer side interfaces. To the bottom, the upper row is the external microphone interface, the headphone jack, the middle row is the accessory port, and the lower row is the USB interface and Type C HDMI. The USB interface is Type-C USB 3.1, which supports USB charging the same as the Z series.
In terms of battery life, Nikon D780 is the same as Z7 and Z6, using EN -EL15b Lithium-ion rechargeable battery, its dimensions and parameters are the same as EN-EL15a/EN-EL15, this series of batteries can be used with each other, but note that USB charging is only supported when EN-EL15b is used. It only supports shutdown charging and does not support side shooting Edge rush. D780 inherits the fine tradition of D750’s long battery life. Thanks to the further enhanced energy-saving design, it can take up to about 2260 photos or about 95 minutes of video on a single charge. This data is far ahead among similar products. It may be because of its excellent battery life that Nikon did not equip this camera with an original handle. Users who want to improve the vertical feel and video battery life may be disappointed.
In terms of storage, D780, like D750, uses dual SD card slots design. Both SD card slots support SD, SDHC and SDXC, and are compatible with UHS-II. The dual card design brings greater flexibility and security. It provides multiple storage options, including saving the same data to two cards for instant backup, or recording RAW and JPEG to different cards at the same time. D780 can also delete two copies of images stored on two cards at the same time through one operation to improve workflow efficiency.
D780 live view Provide a new user interface with i menu. Users can specify 12 functions for the i menu, and customize different designs for photo shooting and video recording as needed. You can use the touch screen to change settings, or use the main/sub command dials and the OK button.
The following are the newly added and improved functions of D780:
900 seconds shutter speed
D780, like D810A, supports long exposure manual mode. The user can customize the setting of “d6: extended shutter speed”. In M mode, the shutter speed can be set to 30, 60, 120, 180, 240, 300, 600, 900 seconds, and the bulb and remote bulb settings can be performed. Since the selectable shutter speed is equivalent to the actual control speed, it is conducive to long-term exposure and post-compositing, and it is convenient to calculate the total exposure time.
Autofocus fine adjustment
Autofocus fine adjustment The function allows users to fine-tune the various lenses used to make the focus accurate when taking photos and videos. When shooting with the viewfinder, you can use the autofocus fine-tuning function to make the camera automatically acquire and save the autofocus adjustment value. With the D780, it is now possible to save the values of the zoom lens at the wide-angle end and the telephoto end separately, thereby improving the autofocus accuracy in the entire zoom range.
Autofocus with eye detection in live view
When auto-area autofocus is used for photos taken in live view, the D780, like the Z6, can use eye-detection autofocus. In AF-C mode, half-press the shutter release button to track the eyes of the moving subject to capture natural portraits. When multiple eyes are detected, you can use the multi selector to select the eye you want to focus on.
From the actual shooting point of view, like Z6 and Z7, when the face occupies a larger screen, it will switch from face detection to eye detection. In addition, there will be The problem of “off-tracking”, including the Z series models, needs to be further improved in this regard in the future.
By using electronic shutter Prevent triggering the movement of the reflector or shutter, thereby avoiding mechanical vibration. This function is effective when users use a telephoto lens to minimize vibration and prevent mechanical wear of the shutter during interval shooting. You can also use silent continuous shooting of 12bit RAW images at a speed of about 12 frames per second. Selected for 14bit RAW images, up to 8 frames per second. This data is comparable to Z6.
D780 can also set high-speed continuous shooting function in the video live view mode, users can shoot at a speed of up to about 120 frames per second about 2 million pixels under the condition of auto exposure/auto focus Images, or about 8 million images taken at a speed of about 30 frames per second. This function uses 1080 120p, 4K 30p video to cut frames to achieve ultra-high-speed continuous shooting.
Interval shooting and time-lapse video
In the past, Nikon models used interval photography to produce time-lapse movies usually requiring post-processing on a computer. This time the D780 can use the interval timer mode to create a photo sequence in the camera, confirm and share immediately. The D780 time-lapse short video is created with a 16:9 aspect ratio, and the camera also saves each frame at the same time. In interval shooting and regular time-lapse photography, Nikon’s exposure smoothing function reduces subtle exposure changes from frame to frame, and when converted to video, it reduces the flicker effect.
Manual preset and point white balance
D780 allows the user to measure a smaller area when shooting in the viewfinder to obtain higher accuracy. This eliminates the need to prepare reference objects or switch to live view mode. At the same time, in live view shooting, you can use the spot white balance function to measure the white balance of the white or gray areas in the screen.
lightening/darkening overlay, special effects
D780 allows users to use the retouch menu to select random pictures to brighten and darken overlays. There is a multiple exposure mode in the photo menu that allows you to select only from the continuous shots.
There are 10 options for special effects and 6 simultaneous recording of RAW images, including super bright, popular, picture description, toy camera effects, model effects and optional colors to further enhance user creativity.
Transfer RAW images to smart devices
SnapBridge version 2.6 allows RAW images to be transferred to smart devices that are directly connected to the camera via Wi-Fi. You can also filter and display photos and videos stored in the camera, setting conditions including file format, date, protected image, rating, etc.
Remote control via Bluetooth connection now provides extended functions. Using a smart device as a remote control, you can take/play back still photos and videos, and press the camera’s shutter release button halfway to perform focusing and other operations. You can also start/stop interval shooting, time-lapse video recording, and focus change shooting.
High-sensitivity image quality test
D780 is equipped with a back-illuminated CMOS sensor with approximately 24.5 million effective pixels. This structure allows incident light to reach the photodiode more effectively, and the image is processed by EXPEED 6. , To achieve the usual sensitivity range of ISO 100-51200. It can be said that the core imaging platform of the D780 is exactly the same as that of the Z6. In order to verify its high-sensitivity image quality, we found the same door Z6 as the reference object. Both cameras are equipped with AF-S24-70mm f/2.8G ED lens and set to RAW. +JPG, matrix metering, 2800K white balance, focal length 50mm, aperture f/8.0. Capture Craftsman 1.6.1 solves RAW.

Left: Z6 Right: D780
From the test results, although Z6 and D780 white balance performance is slightly different, but the noise performance is the same. The images of the two cameras below ISO 800 are relatively clean; the color noise of the two cameras up to ISO1600-3200 is gradually obvious, and the color noise is not obvious; to ISO6400-12800, the light and dark noise and color noise of the two are very close; ISO 25600-51200 , The noise of the two is still consistent; above ISO102400, the pictures of the two are slightly bluish, and a lot of color noise appears. In general, since the imaging platform of the D780 is the same as that of the Z6, the performance of the two is exactly as expected.
As for latitude, the sensor of the previous generation D750 performed well under native ISO100, while the D780 is equipped with the same sensor as the Z6, which is similar to the Z7 sensor. Also increase the amount of signal accumulated in the photodiode as much as possible.
So can D780 continue Nikon’s traditional advantages? This is what the majority of users care about. The author uses the “violent restoration” test method. The camera uses ISO 100, F8 aperture, and performs +3, +2, +1, -1, -2, -3, -4 exposure compensation on the basis of normal exposure. RAW photos with severe overexposure and underexposure are placed in Capture Craftsman 1.6.1 to solve RAW, and the exposure will be restored to the opposite degree.
+1 over Exposure
+1EV Pull back part
+2EV pull back the part
+3EV to pull back the part
From the “violent” test, in the case of +1 overexposure, both cameras can achieve a good “recovery”. In the case of +2 overexposure, D780 can pull back most of the details. When it rises to +3, although D780 can pull back most of the details, we can see that the overexposure scale between 4 and 5 on the upper left corner is difficult to pull back.
-1 ow Exposure
-1EV Pull back part
-2EV pull back part
-3EV pull back part
-4EV pull back to the part
look at the underexposure restoration, the -1 and -2 cameras can basically achieve perfect restoration, and the picture is very pure. When the underexposure is lowered to -3 gear, the dark part will become slightly rough, but it is still better. -Noise starts to appear in the dark part of D780 in 4th gear. Judging from the above real shot test, the Nikon D780’s low-sensitivity tolerance performance is very good, and the performance is comparable to the Z6.
Continuous shooting and tracking focus test
Nikon D780 can use the continuous shooting function of about 7 frames per second when taking photos in live view. This mode also allows 12-bit RAW format Silent continuous shooting at a speed of about 12 frames per second, which is similar to the Z6.
In terms of focusing, D780 live view, like Z6 and Z7, supports “object tracking”, which is similar to 3D tracking.
Next, we test the 12fps silent continuous shooting tracking focus effect of Nikon D780 with AF-S 24-70mm f/2.8G ED, shooting oncoming Jinbei cars, we choose single-point AF with a smaller area .
12fps continuous shooting Effect
chase focus Magnification effect
From the actual shooting, the continuous shooting of the D780 tracks this larger vehicle, and it performs well. Most of the 12 consecutive shots are clear and sharp, but the last few shots are a bit fuzzy. Even though the continuous shooting speed of the D780 is equivalent to that of the Z6 in the viewfinder, because the body is larger and heavier and does not have body anti-shake, the holding posture for this screen viewfinder shooting is not stable and is not suitable for long-term use.
4K ultra-clear video
D780 and Like the Z6, it supports 4K 30p ultra-definition video recording in FX format without clipping. When shooting in FX format video format, full pixel readout is used to output 4K video. This method of oversampling about 2.4 times the source information is similar to the Sony A7III.
Like Z6, D780 can also record full HD 120p/100p video with audio, providing more options in post-production. At the same time, a full HD 4x or 5x slow motion video is generated in the camera.
electronic image stabilization
If the user wants to make high-quality video clips, D780 supports 4:2:2 10-bit HDMI output, and has N-Log, which covers a wide dynamic range of 12 files, and can be shot in highlights or shadows. Record rich gradation information to achieve effective color transition. The camera’s “assisted viewing” function provides a useful way to confirm the general condition of the material while recording with N-log.
In addition, during 10-bit HDMI output recording, the D780 also supports composite logarithmic gamma, which is not available in the Z series, in addition to N-log, which can create high-dynamic-range 4K ultra-high definition with rich highlights and shadows. video. This high dynamic range video format supports the wide color gamut ITU-R BT.2100 of the BT.2020 standard. This function is particularly convenient when users need to quickly provide videos with rich tone levels to HLG-compatible TVs and monitors, because it does not need to convert the data to a high dynamic range format. The camera also has a “assisted viewing” function, which can perform simple grayscale compensation on the recorded video and display it in approximate colors on the LCD monitor, which is convenient for viewing when there is no compatible monitor.
D780 can record the time code in the video data, and also The timecode is saved to the material of the external video recorder via HDMI, so that the material and sound of multiple devices can be synchronized more easily in post-production. Also supports frame skipping. In addition, D780 is compatible with the Atomos open protocol. When the camera’s video recording button is pressed, the start/stop operation of 4K Ultra HD and Full HD recording is synchronized on the camera’s internal memory card and the connected HDMI recorder.
Real shot samples
The following is the AF-S NIKKOR 24-70mm f/2.8E ED VR lens I used with Nikon D780.
Nikon Z6 and D780
passed the previous article In various tests, we can see that the Nikon D780 is a hybrid of the D series and the Z series, calling it the SLR version Z6 worthy of the name. For digital SLRs, the built-in focal plane phase detection AF on the sensor has long existed. For example, Canon’s Hybrid CMOS AF and Dual Pixel CMOS AF have already been applied to SLRs. Nikon, as a late-applied manufacturer, is likely to follow this idea in the future for new D-series SLRs. From the point of view of Nikon users, D780 is positioned between D850 and Z6. Compared with Z6, D780 feels better to hold, dual SD card is more popular and cheaper, supports abundant and relatively cheap F mount lens group, battery life A stronger, no-delay optical viewfinder, a 900s long exposure shutter, and support for HLG video recording; Z6 has a lighter body, greater transfer potential, better Z-mount lens quality, supports five-axis image stabilization, and is more suitable for shooting videos , Whether the user chooses a mature SLR system or a mirrorless system with great future potential is up to the user. D780 is more suitable for D700, D600, DX SLR users to upgrade and give full play to the F-mount lens in their hands. At present, the official price of the D780 body is 14,800 yuan, and the actual price is 13,800 yuan, while the Z6+FTZ adapter ring set is less than 12,000 yuan. Considering the higher cost of the structure of the SLR body pentaprism, mirror, etc., support for motorless AF lenses Even better, the author believes that the price difference between the new and old products is reasonable.
